Mobility extensions to industrial-strength wireless sensor networks
First Claim
1. A method for storing and forwarding messages between a plurality of wireless entities in which at least one of the wireless devices is mobile, the method comprising:
- (a) storing, by a first wireless entity of a plurality of wireless entities, sensor data;
(b) establishing a first connection between the first wireless entity and a second wireless entity of the plurality of wireless entities, the second wireless entity establishing a second connection with a third wireless entity;
(c) receiving, by the second wireless entity from the first wireless entity while temporarily in wireless range of each other, a first message comprising the sensor data, the second wireless entity storing the sensor data;
(d) transmitting, by the second wireless entity, the first message to the third wireless entity;
(e) receiving, by the second wireless entity from the third wireless entity, a second message;
(f) initiating transmission, by the second wireless entity to the first wireless entity while temporarily in wireless range of each other, the second message before transmission of the first message to the third wireless is complete and(g) excluding, by the first wireless entity, retransmission of data indicated in a return receipt, from the transmission.

Abstract
The present solution, in various embodiments, addresses deficiencies in the prior art by providing systems, methods, and devices that enable industrial wireless sensor network nodes, individually or in clusters, to at least: (i) discover quickly and efficiently wireless neighbors that may come within range periodically and/or infrequently, (ii) communicate temporarily with one another in mobile configurations, (iii) transmit and/or receive information and commands from a source to a destination in delay-tolerant network configurations, and/or (iv) transmit and/or receive information and commands from a source to a destination via a mobile cluster that includes a store-and-forward (S&F) surrogate.

10. A system for storing and forwarding messages between a plurality of wireless entities in which at least one of the wireless devices is mobile, the system comprising:
-
a network of a plurality of wireless entities; a first wireless entity of a plurality of wireless entities configured to store sensor; a second wireless entity configured to establish a first connection between the first wireless entity and a second wireless entity of the plurality of wireless entities, and a second connection with a third wireless entity; wherein the second wireless entity is configured to; receive from the first wireless entity while temporarily in wireless range of each other, a first message comprising the sensor data and store the sensor data; transmit the first message to the third wireless entity; receive from the third wireless entity, a second message; and initiate transmission to the first wireless entity, while temporarily in wireless range of each other, the second message before transmission of the first message to the third wireless is complete; and wherein the first wireless entity is configured to exclude retransmission of data indicated in a return receipt from the transmission. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
